Quality Control

Our Octyldimethyl p-Aminobenzoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR, to ensure it meets the high standards required for sensitive applications like cosmetic and pharmaceutical intermediates. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize degradation. Keep away from strong oxidizing agents.
